Avoid possible radio frequency (RF) interference by following these guidelines:
• Do not operate in the vicinity of gasoline or diesel-fuel pumps unless use has been approved and author-
ized.
• Do not operate in locations where medical equipment that the device could interfere with may be in use.
• Do not operate in fuel depots, chemical plants, or blasting areas unless use has been approved and au-
thorized.
• Use care if operating in the vicinity of protected personal medical devices, i.e., hearing aids and pacemak-
ers.
• Operation in the presence of other electronic equipment may cause interference if equipment is incor-
rectly protected. Follow recommendations for installation from equipment manufacturers.
Mobile Application Safety
• Do not change parameters or perform other maintenance of the Gemini G3 modem while driving.

1. PRODUCT OVERVIEW
This document provides the information required for the installation, operation, and verification of the GeminiG3™
wireless radio modem.
This document is designed for use by engineering design, installation, and maintenance personnel.
1.1 GENERAL DESCRIPTION
Available in 700 MHz, 800 MHz, or UHF and in 700-800 MHz Agile Dual-Band (ADB) model, GeminiG3 is a mobile
radiomodem aimed at the public safety and public utility markets. It integrates all the necessary hardware for data-only
vehicular installations up to but not including the laptop PC and its application software.
Examples of applications are:
1. Database inquiry systems.
Small number of brief messages, (usually from the mobile station) with fairly long responses.
2. Computer-aided dispatch (CAD).
Large number of messages, (usually from the base station) with very brief responses.
3. Autonomous Automatic Vehicle Location (AAVL).
Using built-in GPS receiver, determines position, speed and direction of fleet members.
The GeminiG3 radiomodem is made-up of:
• A main transceiver
• An auxiliary receiver for Parallel Decode™
• A 10 to 25-Watt adjustable power amplifier (700 MHz), 10 to 35 (800 MHz), 10 to 40 (UHF), 12.5 to 25 (UHF-
ACMA)
• A Gemini Processor/Modem board with DSP modem
• An integrated OEM 12-channel GPS receiver.
1.1.1 FEATURES
• ADB model allows 700/800 MHz automatic band and bandwidth switching capability during roaming.
• Parallel Decode™ (PD) technology featuring dual receivers for added decode sensitivity in multi-path and
fading environments.
• Native IP mobile model having “Stateless Data Compression” and “Protocol Reduction”, that works with
TCP/IP and UDP, uses standard 10/100 BaseT Ethernet RJ-45, and automatic MDIX to get the most efficient use of user available bandwidth without requiring a dedicated server or gateway. It acts as a router,
interfaces with any Ethernet device or Native TCP/IP application, and has two RS-232 ports that can be
6
configured as terminal servers. Using an in-car hub or switch makes adding other peripherals, such as a
Channel Type
UHF-
Modula-
camera, possible.
• Sophisticated DSP-based modem design provides added system performance, fewer retries and more ef-
fective throughput.

2. INSTALLATION
2.1 PLANNING THE INSTALLATION
2.1.1 OVERVIEW
To ensure trouble-free, efficient installation, start by inspecting the vehicle to determine the optimum position for
GeminiG3 unit and its antennas as well as the routing of all associated cabling and wiring.
2.1.2 LOCATION
Often, installations in cars are done in the trunk, underneath the back window ledge or on the trunk floor. In vans
and small trucks, it is usually done in the back of the vehicle. In large vehicles, it is often done in the front cabin.
Be sure to place the GeminiG3
• The LEDs can be seen (as an aid in troubleshooting)
• Access to the antenna connectors is possible without removing the unit
• Sufficient air may flow around the unit to provide adequate cooling
unit in such a way that:
The GeminiG3 unit is not fully waterproof, therefore it should be mounted sufficiently away from an opened trunk
lid or opened tailgate, windows or doors to avoid exposure to rain and/or snow. It also minimizes the chance that
material can be accidentally thrown on the unit or of someone bumping against it.
2.1.3 CABLE PATH
Try to route the cables away from locations where they would be exposed to heat (exhaust pipes, mufflers, tailpipes, etc.), battery acid, sharp edges, mechanical damage or where they would be a nuisance to automobile mechanics, the driver or the passengers.
Keep wiring away from automotive computer modules, other electronic modules and ignition circuits to help prevent interference between these components and radio equipment.
Try using existing holes in firewall and trunk wall and the channels above and below or beneath the doors, channels through doors and window columns that are convenient to run cables and wires.
Whenever possible, install conduit in which to run the cables.
2.2 WARNINGS
Before starting installation, review all of the following warnings.
9
2.2.1 RF RADIATION WARNING
Recommended safety guidelines for the human exposure to radio frequency electromagnetic energy are contained
in the Canadian Safety Code 6 and the Federal Communications Commission (FCC) Bulletin 65. Proper installation
of the transceiver antenna of GeminiG3 radiomodem as summarized in section 2.5 will result in user exposure substantially below the recommended limits for the general public.
Qualified personnel must do all antenna installations. See paragraph 2.5.2 for recommended antenna positioning.
Transmissions when persons or animals outside the vehicle are within two feet of the antenna may result in radio
energy radiation burns or related injuries.
2.2.2 INTERFERENCE WITH VEHICULAR ELECTRONICS
Certain vehicle electronic devices may be prone to malfunction due to lack of protection from radio frequency energy present when transmitting.
It includes, and is not limited to:
• Electronic fuel injection systems
• Electronic anti-skid braking systems
• Electronic cruise control systems
If the installation vehicle contains such equipment, consult the dealer for the make of vehicle and enlist his aid in
determining if such electronic circuits will perform normally when the radio is transmitting.
2.2.3 SECURE MOUNTING
For vehicle occupant(s) safety, mount the GeminiG3 radiomodem securely so that the unit will not break loose in
case of an accident or violent maneuvers.
2.2.4 EXPLOSIVE ENVIRONMENTS
Operation of vehicular radio transmitters in explosive environments may be hazardous and conventional safety
precautions must prevail. These include and are not limited to:
• Transmitting while fuelling the vehicle. Do not carry fuel containers in the same compartment as the
GeminiG3 unit.
• Dynamite blasting caps may explode when transmitting radio operation takes place within 500 feet.
Always obey the “Turn Off Two-Way Radios” signs posted at sites where dynamite is being used.
If transporting blasting caps, (check applicable local bylaws) be aware to:
a) Carry the blasting caps in an appropriate metal container having a soft cushioning lining.
10
b) Suppress transmissions whenever the blasting caps container is being loaded or unloaded into or
from the vehicle.
2.2.5 INSTALLATION IN VEHICLES POWERED BY LIQUEFIED GAS.
GeminiG3 radiomodem installations in vehicles powered by liquefied petroleum gas with the LP-gas container in
the trunk or other sealed-off space within the interior of the vehicle must conform to the National Fire Protection
Association Standard NFPA 58 which requires:
• Space containing radio equipment shall be isolated by a seal from the space containing the LP-gas
container and its fittings.
• Outside filling connections shall be used for the LP-gas container.
The LP-gas container space shall be vented to the outside of the vehicle.
2.3 PHYSICAL UNIT
2.3.1 RECOMMENDED TOOLS AND SUPPLIES
• Electric drill for mounting holes
• Hammer and center punch
• Tie-wraps
• Drills and circle cutters as needed according the size of screws (or nuts and bolts) used.
• In-line “Power meter” capable of measuring forward and reflected power at the operating frequency
of the radio.
2.3.2 PHYSICAL MOUNTING
a) Start by running all the cables (DC power, CAT5 Ethernet and optional PC RS-232 as well as all anten-
nas cabling) prior to mounting the GeminiG3 unit to assure the feasibility of the planned cable routing.
b) Be sure to leave sufficient slack in each cable so the GeminiG3 unit may be removed from the mount-
ing bracket for servicing with the power applied and the antenna attached.
c) GeminiG3 unit is ready for installation.
Cautions:
• When drilling mounting holes, be careful to avoid damaging some vital part of the vehicle
such as fuel tanks, transmission housing etc. Always check how far the mounting screws extend below the mounting surface prior to installation.
11
• Use of drill bit stops is highly recommended.
• After drilling, remove all metal shavings before installing screws.
• Do not overtighten self-tapping screws.
1. Once you have found a suitable mounting position for GeminiG3 radiomodem, hold the unit and the unat-
tached mounting bracket in the proposed mounting position and check that there is clearance behind the
unit for the heatsink, cables, etc. Check that the position provides a large enough flat surface that the
bracket will not be distorted when installed.
Exterior Dimensions: 6.3 x 2.5 in. - Slot Dimensions: 1.0 x 0.2 in.
Figure 1 - Mounting plate and slot dimensions
2. Using the installation bracket as a template, mark the four locations for drilling (see Figure 1). Again, en-
sure that drilling at the selected points is safe and will not cause damage.
3. Indent the drilling positions with a center punch. Drill holes sized for the self-tapping screws or for the
nuts, bolts and lock washers used.
Figure 2 - Bracket installation
Caution: Slightly reduce the size of the drilled holes when using self-tapping screws in thin metal.
4. Install the bracket without distorting (see , bolts and lock washers used.
5. Figure 2 - Bracket installation
12
6. Securely mount GeminiG3 unit
to the installed bracket using the four supplied metal shoulder screws as
shown in Figure 2 above. Push the screws through the rubber grommet and fasten securely to the unit. Do
not over tighten.
Figure 3 – Rubber grommet and shoulder screw details
5. Drill any additional holes as required for routing all cables and fit holes with suitable grommets or bush-
ings whenever required.
2.4 ELECTRICAL INSTALLATION
2.4.1 ELECTRICAL REQUIREMENTS
GeminiG3 radiomodem is designed to operate from a 13.8Vdc nominal car battery (negative ground) and requires
currents up to 12.0A. It will tolerate a supply voltage range of 10.9 volts to 16.3 volts.
In vehicles with a 24 VDC electrical system (mostly in trucks), it is essential to provide a suitably rated 24/12 VDC
converter to isolate the unit from the battery and protect it against excessive voltage.
Warnings:
Always disconnect GeminiG3 radiomodem’s DC power lead before connecting a second battery, using
power from another vehicle or power boosting (e.g. when “jump starting” the vehicle).
2.4.2 ROUTING OF POWER CABLE
1. Start by disconnecting the vehicle’s battery unless specifically prohibited from doing so by the customer,
vehicle manufacturer, agent or supplier.
Note: In this event, exercise extreme caution throughout the installation and fit the fuse only
when the installation is complete.
13
The 22 feet (6.7 meters) long power cable consists of three wires attached to a Packard Electric “Weather-Pack” connector (DC power

Figure 4 - DC Power Connector
The DC Power connector has:
• At position “A”, the smaller red switch-sense wire (commonly to ignition)
• At position “B”, the blue ground wire
• At position “C”, a larger red B+ DC power wire (MUST be unswitched)
3. Place this connector at GeminiG3 unit’s radio power input location. Do not connect at this time. See para-
graph 2.6, “Completing the physical installation”.
4. Carefully route both the B and the C wires to where the in-line fuse holder will be installed, usually as
close to the vehicle’s battery as practicable. Ensure that leads do not chafe on any metal part(s). Secure
the wires at several locations along their length.
Caution:
Use proper crimping tool. Common pliers are NOT acceptable.
Warning:
The DC Power lead must be unswitched
5. Insert the negative (blue) lead into one of the appropriate connector lug and crimp solidly to force the
metal contacts onto the wires.
6. Repeat the step above for connecting the red DC power lead.
7. Attach the positive lead at the battery positive terminal. Attach the negative wire at the vehicle end of the
battery ground cable.
If the negative cable is connected directly to the battery negative terminal, it
should be fused in case of failure of the vehicle’s ground cable.
14
Ensure tight and secure connections.
8. Fasten the fuse holder and leads.
9. Carefully route the “A” wire to where the connection will be made for switch sensing.
• Connect to “Ignition” if you wish to have GeminiG3 unit turning ON and OFF dependent on the vehi-
cle’s ignition key.
• Connect to “Accessory” if you wish GeminiG3 unit to be available when the engine is not running, but
still dependent on the ignition key.
• Connect to a user-supplied control switch.
• In installations equipped with a “ChargeGuard”, connect to the controlled-side of the ChargeGuard
(remembering that the DC Power lead must NOT be switched).
10. Make appropriate connections.
Cautions:
Where scraping to bare metal was required, and at the battery posts where wire ends and lugs may
be exposed, apply anti-corrosion compound.
Insert the fuse only when installation is complete and ready to test.
11. At the GeminiG3 radiomodem’s position, neatly coil cable slack and attach securely.
2.5 ANTENNA
The main transmitter antenna must be vehicle-mounted to provide a separation distance of 50 cm or more
from all persons and the antenna gain must not exceed 5dBi (with a 1.6dB cable loss).
2.5.1 RECOMMENDED TOOLS AND SUPPLIES
• Circle cutter, hole saw or socket punch for antenna
• Appropriate crimping tool for type of connection present on the radiomodem unit

Referring to Figure 5, the GeminiG3 radiomodem commonly uses three separate antennas:
• “T” - Main transceiver -
Constraints are the limit of 50 cm (see section 2.5 above) and omni-directional factors
• “R” - Auxiliary receiver –
Constraints are the receiver spacing of at least 5/8 λ (wavelength) from transceiver antenna and omni-
directional requirements
• “G” - Global Positioning System (GPS)
Constraints are TX spacing of at least 24-in/60.96 cm from all transmitting antennas and a clear view of
the sky.
.3cm
Figure 5 - Antenna spacing
For the optimum antenna spacing at the frequency you are using, consult System Engineering.
For installation of ground-plane dependent antennas, the center of the metal surface used for mounting is
preferable for best omni-directional pattern. For ground-plane independent antennas, installation may be
close to the edges of the surface.
Install the antennas in one of the following positions:
• Most preferred for all antennas: centerline of roof. For transmitter antenna, it is the ONLY acceptable po-
sition.
• Less preferred for receiver antenna: trunk lid, providing distance to transmitting antenna is respected
whether lid is opened or closed.
16
• Much less preferred, but permissible for receiver antenna: left or right rear fenders, just in back of rear
window
• Least preferred, but permissible for receiver antenna: left or right front fenders, ahead of windshield
Proximity to other vehicle-mounted antennas may cause mutual interference especially at higher frequencies.
2.5.3 ANTENNA INSTALLATION
1. Route good quality 50-ohm coaxial cables (e.g. RG-223) from each of the selected antenna positions to
the position where the GeminiG3 unit is mounted.
2. Terminate the end at each of the antenna positions with the appropriate connector for the antenna used
and make the connection.
3. At the GeminiG3 unit position, cut the three cables to length and terminate with the appropriate plug. For
the transceiver and the auxiliary cables, use the proper crimp plug for the connections present on the
radiomodem. For the GPS
4. Positively identify the transceiver plug and connect to the left rear of GeminiG3 unit.
5. Positively identify the auxiliary receiver plug and connect to the front left of GeminiG3 unit to the RX po-
sition.
1
, use a SMA connector.
6. Connect the SMA connector to the GPS position below the auxiliary connector position.
7. Do not skip this last step, trust us; it is an important one. To complete the installation, tie-wrap together
the auxiliary and the GPS antenna cables at a point about two inches in front of the unit. It will be much
easier hereafter to correctly identify which plug goes where. You DO NOT want to cross the auxiliary plug
with the transceiver plug.
2.6 COMPLETING THE PHYSICAL INSTALLATION
To complete the physical installation and prior to testing the GeminiG3 radiomodem:
• Connect DC Power cable’s connector to the GeminiG3 unit connector until you hear a click as the two
parts snap together.
• Re-check that all other connections are secure (antennas, PC, etc.)
• Switch vehicle ignition ON.
17
You are now ready to check for normal operation and to run the GeminiG3 Web Interface program for testing
or trouble-shooting
2.7 CHECKING OUT NORMAL OPERATION
Check that the vehicle ignition is ON.
1. Check for proper operation of the GeminiG3 LEDs as per Table 2 on page 20.
2. Using the GeminiG3 Web Interface program and an in-line wattmeter, check forward & reverse power to
confirm main antenna installation (as per section 4).
3. Check the RF Data Link with a base station that can be heard (see section 4.7.7.1).
4. If user application and its base station are available, test the installation by going through a normal se-
quence of transmitting and receiving messages.

4. OPERATION & CONFIGURATION
Instructions and examples given in this manual are based on E-DBA operating software version at the time of
writing this document and may not apply to earlier or later software versions. Screen captures used throughout this document may vary from actual screens.
4.1 BROWSER-BASED INTERFACE
A built-in web server makes configuration and status monitoring possible from any browser-equipped computer, either locally or remotely. Status, configuration, and online help are available without requiring special
client software. Setup is password-protected to avoid tampering or unauthorized changes.
Both the configuration parameters and operating firmware can be updated remotely, even over the RF network itself, using the standard File Transfer Protocol (FTP).
